ROD-ROLLING MILL.

SPECIFICATION forming part of Letters Patent No. 415,784, dated November26, 1889.

Application filecl August 30, 1889' SeriaYNo. 3221165- (N model.)

To all whom it may concern.-

Be it known that I, GUSTAF JANSSON, of Munkfors, in the county ofWVermland, Sweden, have invented certain new and use ful Improvements inRod-Rolling Mills; and I do hereby declare that the following is a full,clear, and exact description thereof, reference being had to theaccompanying drawings, forming a part of this specification, and

in which V Figure 1 represents a top or plan view of so much of arod-rolling mill as is necessary to illustrate my improvements. Fig. 2is a central vertical longitudinal section through the parts shown inFig. 1, taken on line a of said figure. Fig. 3 is a transverse sectiontaken on line I), Fig. 1, looking in the direction indicated by thearrow. Fig. 4 is a detached side View of my improved protecting- 2ohood, hereinafter more fully described; and Fig. 5 is a modification inthe construction thereof, also hereinafter more fully described.

My invention is designed more particularly for continuous rod-rollingmills, but is also 2 5 applicable to other kinds of rolling-mills. Thepurpose thereof is to provide means whereby two or more rods may betreated at the same time and thus admit of an increased production. Saidinvention also serves to reduce the liability of injury to the workmenby confining the rods within proper limits in case of breakage inpassing through from one set of guides to the next.

It consists of a hood or cover so constructed 3 5 and arranged as toprotect the wire upon the top and sides in its passage between thedelivering and receiving guides of a rod-rolling mill, as will behereinafter more fully set forth.

In order that others may better understand the nature and purpose of mysaid invention, I will now proceed to describe it more in detail.

In the drawings, A A and B B represent the housings for two pairs ofreducing-rolls O C and D D.

E F are the guidebars which support the guide-boxes G H, which in turnhold the delivering-guide. I and receiving-guide J, re-

spectively.

All of the above parts may be of ordinary well-known construction andarrangement, and therefore require no detailed description.

The part K represents my improved hood or cover, which fits over thetops and sides of the guide-boxes G H and rests at each side thereof onthe guide-bars E F, said hood extending nearly up to the reducing-rollsat eachend and over the whole space between each set of guides, so as toprotect the rods in their passage between the delivering and receivingguides, as previously stated.

In practice I prefer the construction shown by the first four figures ofthe drawingsviz., of arranging the hood over the guide-boxes andsupporting the same as specified; but as the same result may readilybeaccomplished in various other ways I do not limit myself thereto. Anillustration of one other Way is shown by Fig. 5. In this instance thesame result is effected by forming the hood integral with thetopdelivery-guide, said guide being extended over the space betweenthetwo sets of guides to form the hood K. As will be apparent, the sameresult may thus be pro- -duced; but the construction is not as desirablein practice, as it does not permit of the easy removal of said hood whenoccasion requires such removal.

By the first-described construction and arrangement the hood is made sothat it may be easily detached in the following manner: One end of thehood is provided at each side with a recessed portion 0 to form thehooks cl, adapted to catch and hold upon the under edge of the guide-barF, as is shown in Fig. 2, while to each side of its opposite end,outside of the hood, is pivoted a latch e, the two latches beingextended up above the hood and 0 connected by thetransverseoperating-ban die 6, whereby the lower hooked ends 6 of thelatches may be engaged and disengaged to and from the bottom edge of theguide-bar E. (Shown by full and dotted lines in Fig. 2.) 5 As the handleportion extends considerably back of the hooked ends and pivots of saidlatches, it is obvious that when fitted in position the hood is heldsecurely in place, and at the same time may be readily detached I00 whenrequired by simply swinging the handle 6 so as to disengage the hookedends from the guide-bar, and lifting said hood so as to disengage itshooks d d from the guidebar F in said lifting operation. By thusprotecting the rods at the top and sides at the points mentioned in arolling-mill it is also obvious that any desired number of rods maybetreated at the same time with perfect safety to the workmen, as in caseof the breaking and snarling of any one of the rods beingtreated theothers are in no Wise affected or retarded in their progress, as wouldbe the case were such protecting-hoods not employed. By this provisionthe danger of injury to the workmen is not only greatly lessened, butthe production largely increased by the treatment of several rods at thesame time, as aforesaid.

Having now fully described my invention, what I claim therein as new,and desire to secure by Letters Patent, is

1. In a rod-rolling mill, a hood or cover so constructed, arranged, andfastened in position as to protect the rods in passing from thedelivering-guides to the receiving-guides, substantially as and for thepurposes set forth.

2. In a rod-rolling mill, the combination of the delivering-guides andtheir boxes and the receiving-guides and their boxes with a hood orcover so constructed, arranged, and fastened in position as to protectthe rods upon the top and sides thereof in passing from thedelivering-guides to the receivi11g-guides,substantially as and for thepurposes set forth.

8. In a rod-rolling mill, the combination of the delivering-guides andtheir boxes, the receiving-guides and theirboXes, and the guidebars witha hood or cover so constructed, arranged, and fastened as to protect therods upon the top and sides in passing from the delivering-guides to thereceiving-guides, substantially as and for the purposes set forth.

In a rod-rolling mill, the combination of the delivering-guides andtheir boxes, the receiving-guides and their boxes, and the guidebar witha hood or cover so constructed and arranged as to protect the rods uponthe top and sides in passing from the deliveringguides to thereceiving-guides, and means for fastening said hood or cover inposition,substantially as and for the purposes set forth.
